Aireplay-ng or mkd4 better for disrupting wifi device’s connection? [closed]

I have some experience with aireplay-ng but recently found out about mkd4. My question is which of these tools is more effective in disrupting the wifi connection of a device?

I heard mkd4 both deauthenticates and disassociates a device, but I also heard aireplay-ng is faster. Which sounds to me like a device reconnecting becomes less likely.

Anyone have some more info about this?
